2 Claims.

My invention relates to a metal window of the particular type disclosedin U. S. Letters Patent No. 2,112,634 issued to me March 29, 1938.

The principal objects of my present invention are, to generally improveupon and simplify the construction of the metal window covered by myaforesaid patent, as well as other existing forms of metal windowshaving swinging sash, further, to provide in a metal window thatincludes a plurality of sash frames hinged so as to swing outwardly intoinclined positions relative to the vertical plane occupied by the windowframe and further, to construct the swinging sash so that panes of glassmay be easily and quickly inserted and secured in the sash.

Further objects of my invention are, to construct the various parts ofthe window so as to provide maximum protection against entry byintruders, further, to construct the window frame and swinging sash soas to provide a highly efficient air, dust, and rain-proof window, andfurther, to provide a window that is entirely fireproof.

A further object of my invention is, to provide relatively simple andeasily operated means for simultaneously swinging the glazed sash intoopen or closed position.

With the foregoing and other objects in view, my invention consists incertain novel features of construction and arrangement of parts thatwill be hereinafter more fully described and claimed and illustrated inthe accompanying drawings in which:

Fig. 1 is a front elevational View of a metal window constructed inaccordance with my invention.

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1.

Fig. 3 is a perspective view of the two members that combine to form thecentrally arranged ver tical member of the window frame. H

Fig. 4 is a vertical section taken on the line 44 of Fig. 1.

Fig. 5 is an enlarged horizontal section taken on the line 55 of Fig. 4.

Fig. 10 is an enlarged horizontal section taken on the line |0l0 of Fig.8.

Fig. 1i is an enlarged detail taken approximately on the line II|I ofFig. 1 with intermediate parts broken away.

Referring by numerals to the accompanying drawings which illustrate apreferred embodiment of my invention, In designates the horizontallydisposed top member or rail of the window frame, H the verticallydisposed side members or stiles and I2 the lower rail. These rails andstiles are preferably formed from heavy sheet metal and, extendingupwardly from the outside edge of the top rail i0 is a flange I3.

The outer portions of the stiles l l terminate in outwardly projectingflanges l4 that occupy the same vertical plane with the flange I3 and,formed between said flanges l4 and the main body portions of the stilesII are portions [5 that occupy inclined planes of approximatelyfortyfive degrees relative to the planes occupied by the bodies of thestiles I l and their flanges l4.

Depending from the outer edge of the lower rail I2 is a flange I6 thatoccupies the same vertical plane with flanges l3 and I4 and, secured bywelding or otherwise to the lower portions of the flanges M of thestiles and positioned immediately above the outer portion of lower railI2 and itsfiange I6 is a transverse rail having an intermediate portionI! that occupies an inclined plane of approximately forty-five de- Fig.6 is an enlarged horizontal section taken on the line E--6 of Fig. 4. 1

Fig. 7 is a detail elevational View taken approximately on the line 1--1of Fig. 4 with parts in vertical section.

Fig. 8 is an elevational view of one of the grees and which correspondswith the inclined portions I5 of the stiles II. The inner portion ofthis rail terminates in a vertically disposed flange I8 that occupies aposition between the lower portions of the stiles ll, slightly insetfrom the corners between the inclined portions l5 and the main bodyportions of the stiles and, projecting forwardly from the lower portionof the inclined body I! of this rail is a horizontally disposed flange I9 that projects a short distance forwardly from the vertical planeoccupied by the front faces of the flanges l3, I4, and H5.

The ends of the upper and lower rails 10 and I 2 are rigidly secured inany suitable manner, preferably by welding, to the ends of the stiles lI, thus providing a strong and substantial frame for the window.

In the construction herein illustrated, I have shown a window having sixsashes arranged in pairs, one above the other, but it will be understoodthat the window frame may be made larger or smaller so as to accommodatea number of sashes, greater or less than six.

Arranged midway between the stiles H is a vertically disposed rail 20 ofangle bar shape in cross section with flanges of equal width and theends of this intermediate rail are rigidly fixed, preferably by welding,to the top and bottom rails l and I2 respectively. This intermediaterail is arranged so that its central line, or the apex between itsflanges, occupies approximately the same vertical plane with the outerfaces of the flanges l3, l4, and I6 and, thus the outer faces of theflanges of the central rail occupy inclined positions that correspondwith the inclined positions of the portions l of the stiles.

Suitably secured, preferably by welding, to the under side of top railID a short distance inwardly from flange I3 is the upper inner portionMa transversely disposed rail 2| that extends outthe latter occupying aposition in front or out-' wardly from the flanges l3 and I4. This railprovides a point of attachment for the hinges that are carried by theupper sash and in addition said rail provides an effective dust andweatherproof closure between the upper ends of the upper sash and thetop rail 10 when the sash are closed.

Spaced equi-distant apart from each other and from the top rail 10 andbottom rail l2 are transversely disposed rails 23, the ends of which arerigidly fixed, preferably by welding, to the stiles H and theintermediate portions of these transverse rails are connected,preferably by welding, to the intermediate member 25. Each of theserails 23 is provided on its upper inner edge with a verticallydisposedflange 24 and on its lower outer end with a horizontally disposed flange25, thus conforming in a general way to the cross sectional shape of therails 2| and I].

The inclined portions I5 of the stiles and the inclined flanges of theintermediate vertical rail provide beveled seats for the correspondinglybeveled upright side members of the window sash. The upper surfaces ofthe inclined portion I! of the lower rail and the upper surfaces of theinclin'ed portions 23 of the intermediate horizontally disposed railsprovide beveled seats for the correspondingly beveled lower rails of thewindow sash, while the under surface of the inclined portion 2| of theupper rail and the under surfaces of the inclined portions 23 of theintermediate rail provide beveled seats for the correspondingly beveledupper rails of the window sash. Thus, the frame comprising upper andlower rails It and I I, together with upright rails or stiles II and thetransverse rails l1, 2|, and 23 constitute a strong and substantial,practically one piece, window frame having a plurality of sash openingsof equal size for the accommodae tion of the hinged glazed sash.

Each sash comprises a rectangular frame that includes an upper rail 26,a bottom rail 21, and upright side rails 28, each frame being cast in asingle piece. The upper rail 26 is provided with a beveled upper face29. which, when the sash is closed makes direct contactwith the undersurface of the inclined member 2| of thetop rail or the inclinedportions 23 of the intermediate horizontal rails.

Formed integral with the ends of the top rails 26 are lugs 30 that formpoints of attachment for the inner plates of hinges 3! the outer platesthereof being suitably secured to the flange 22 of the upper rail 2| orto the flanges 25 of the intermediate horizontal rails. The side rails28 of each sash frame are provided on their outer edges with beveledfaces 32 which, when the sash are closed fit snugly against the outerfaces of the inclined portions 15 of the stiles II.

The lower rails 21 are provided on their under sides with beveled faces33 which, when the sash are closed fit snugly against the upper surfacesof the inclined portions 23 of the intermediate rails and upon theinclined central portion of the lower rail l1.

Thus, when the parts of the window are properly constructed and the sashare closed, weatherproof joints are formed between the sash and thewindow frame and immediately above each sash is a transverse rail, suchas 2l or 23, that is inclined and which projects beyond the outer faceof the window frame to provide an effective dust and rain shield.

Each upright side rail 28 of each sash is provided on its front inneredge with a pair of inwardly projecting flanges 34 which function asbearings for the side edges of the pane of glass that is positioned inthe sash frame and, formed on the intermediate portion of each uprightside member 28 adjacent the rear edges thereof are inwardly presentedflanges 35 which also serve as bearings and retainers for the pane ofglass positioned in the frame. The flanges 35 also function as points ofconnection for links forming a part of the sash raising and loweringmeans and which will be hereinafter more fully described.

Formed on the lower portions of the inner edges of the upright sidemembers 28 of the sash frameand on the rear edges of the end portions ofthe bottom rail are flanges 35 which serve as bearings for the panes ofglass positioned in the frames and, formed on the intermediate portionof the front edge of each bottom rail 21 is a flange 31 which alsofunctions as a bearing for the panes of glass.

The flanges 34 and 35 on the upright side rails 28 and the flanges 35and 31 on the bottom rails are spaced apart laterally of said rails asuflicient distance to accommodate a pane of glass such as G and whichwhen inserted from the top of each frame fits snugly" therein betweenthe various flanges and with the'upper edge of the pane of glasspositioned directly behind the lugs 30 on the upper rail 29 of the sash.

Such construction enables the panes of glass to be easily andconveniently inserted in the sash, thus facilitating replacements in theevent of breakage of the glass and, to secure the panes of glass in thesash putty as designated by P, or the like, is applied to the faces ofthe glass along the side and bottom edges thereof between the flanges34, 35, 36, and 31 and if desired putty may be placed between the edgesof the panes of glass and the metal rails of the sash against which saidedges engage, such latter provision insuring air and weather-proofjoints between the glass and metal.

In the event that it becomes necessary to replace broken panes of glassafter the window has been assembled, the sash must be swung outwardlyinto position where the panes. of glass while being inserted will clearthe inner portions of the top rail l0 and the upper inner portions ofthe intermediate rails 23.

Arranged for vertical sliding movement upon the rear side of the flangedintermediate vertical rail 20 is a channel 38, the same being somewhatshorter than rail l0 and, formed in the central portion of the web ofthis channel adjacent its upper and lower ends are vertically disposedslots 39 for the accommodation of pins 40 that project from the rail 28and, the ends of these pins that pass through the web of the channelreceive nuts 4!, thus maintaining the channel for sliding movement onthe rear side of the rail 20.

Pivotally connected to the flanges of channel 38 are the upper ends ofadjustable links 42 such as turn buckles, the lower ends thereof beingpivotally connected to brackets 43 that are mounted on the flanges 35that are formed on the upright side members 28 of the sash frames. Theseadjustable links or turn buckles 42 are arranged in pairs with one linkconnecting one of the side members 28 of each sash with the slidingchannel 38.

The means utilized for imparting vertical sliding movement to channel 38includes a housing 44 that is secured on top. of the central portion ofbottom rail [2 and, journalled for rotation in the removable inner wall45 of said housing is the hub portion 46 of a pinion 41, the teeth ofwhich mesh with the teeth of a pin tooth gear 48 that is mounted forrotation within the lower portion of housing 44 on top of bottom railI2. This pin tooth gear has a hub 49 that has bearing in an openingformed in rail l2 and secured by a pin or otherwise to the pin toothgear and its hub is the lower end of a vertically disposed threadedshaft 50. This shaft passes through a nut the latter being held in thelower portion of a channel 38 by means of pins or screws 52 that passthrough the flanges of said channel into the sides of the nut and, inorder to maintain this nut in operative position lugs 53 project fromthe rear side of said nut and bear on the face of the web of the channel38.

To maintain the pin tooth gear in operative position on the top ofbottom rail I2, fingers 54 project from the lower portion of the coverplate 45 of the housing over the upper ends of the teeth of said gearand thence downwardly so as to bear on the flat upper face of the pintooth gear between its teeth and the threaded shaft 58 (see Figs. 6 and7).

Formed in hub 46 of pinion 41 is a non-circular recess 55 that functionsas a socket for the reception of one end of a crank or other tool thatis utilized in rotating the pinion.

To swing the glazed sash on their hinges, a tool such as a crank isutilized for imparting rotary motion to pinion 44, which pinion drivesthe pin tooth gear 48, thus imparting rotary motion to the threadedshaft 50 which moves nut 51 upwardly or downwardly as the case may be.When opening movement is applied to the sash, shaft 58 is rotated so asto cause nut 5| to move downwardly and as the nut is connected tochannel 38 by means of the pins or bolts 52, said channel is moveddownwardly on the flanged intermediate member 20.

Through the turn buckles 42 arranged between the sliding channel and thesash, the latter will be swung outward to the desired degree ofangularity, thus giving ample ventilation through the window.

To close the sash, threaded shaft 50 is rotated so as to cause the nutto move upwardly on said shaft, thus correspondingly drawing the turnbuckles upwardly and moving the sash into closed positions. When closed,the beveled upper faces on the top rails 26 of the sash fit snuglyagainst the under sides of the beveled portions of the intermediatehorizontal rails and the beveled portion of the rail 2| that ispositioned beneath top rail ll! of the window frame. When the sash areclosed, the beveled lower faces 33 of the sash bear on top of thebeveled portions of the intermediate rails 23 and on the beveled portionI! of the rail that is positioned just above the bottom rail l2 of thewindow frame.

Likewise, the beveled faces 32 on the upright side members 28 of thesash bear snugly against the correspondingly beveled portions l5 of thestiles II and against the faces of the inclined flanges of intermediatevertical rail 20. Thus when the glazed sash are closed, weather-proofjoints are provided between the rails of the sash and the various railsof the window frame. Should any play or lost motion develop in any ofthe hinged sash, this can be readily adjusted and taken up by propermanipulation of the turn buckles 42. I

The transverse rails 2|, 23, and H, having their ends welded to theupright side members or stiles of the window frame, materially reinforcethe latter and provide an extremely strong and substantial structure, inaddition to providing an outwardly presented transversely disposedshield immediately above the upper ends of the hinged sash.

An especially desirable feature of my invention is, the construction ofthe sash frames which enables broken panes of glass to be readilyremoved and replaced by new panes, without the necessity for detachingthe sash frames from the window frame.

Thus it will be seen tha I have provided a metal window that isrelatively simple in construction, inexpensive of manufacture and veryeffective in performing the functions for which it is intended.

It will be understood that minor changes in the size, form andconstruction of the various parts of my improved metal window, may bemade and substituted for those herein shown and described, withoutdeparting from the spirit of my invention, the scope of which is setforth in the appended claims.

I claim as my invention:

1. In a metal window, a sash formed in a single piece and comprising topand bottom rails and vertically disposed side rails, a plurality ofstaggered flanges formed on the inner edges of the vertically disposedside rails and the bottom rail of said sash, a pane of glass positionedin said sash with its side and lower edges disposed between said flangesand which flanges are spaced apart longitudinally of the rails on whichthey are formed in order to form longitudinally disposed spaces for thereception of putty that secures the pane of glass to said sash.

2. In a metal window, a sash being formed in a single piece andcomprising top and bottom rails and vertically disposed side rails, aplurality of staggered flanges formed on the inner edges of thevertically disposed side rails and the bottom rail of said sash, a paneof glass positioned in said sash with its side and lower edges disposedbetween said fianges, which flanges are spaced apart longitudinally ofthe rails on which they are formed in order to form longitudinallydisposed spaces for the reception of putty that secures the pane ofglass to said sash and the upper edge of said pane of glass beingpositioned behind the rear edge of the top rail of said sash.
